<p><code>measureme</code> gets some love from the wider Rust community (and also a potential bug report):</p>

<blockquote>
<p>It appears that -Z codegen-passes is basically now made obsolute by a more precise (and hopefully more accurate) self-benchmarking method, a -Z self-profile flag with a set of tools appropriately called measureme. This outputs some binary profiling data that then gets crunched and displayed by one of measureme’s tools, summarize. Or even better, it can output ♥flame graphs♥.</p>
